SUPPORTING-FRAME FOR CHECK-ROWERS.

SPECIFICATION forming part of Letters Patent No. 635,839, dated October 31, 1899.

Application filed July 22, 1899. Serial No. 724,746. (No model.)

To all whom it may concern;

Be it known thatI, JOSEPH WILLIAM BET- TENDORF, a citizen of the United States, and a resident of Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Supporting-Frames for Check-Rowers, of which the following is a full, clear, and exact description.

The object of my invention is to provide such a connection between the supportingframe and the trailing spade-wheel marker of a check-rower corn-planter that said marker will travel in the straight line of draft and not be deflected therefrom by the deviations of the draft-animals or by the unevenness of the ground over which the said markers travel. This I accomplish by the means hereinafter fully described and as particularly pointed out in the claims.

In the drawings, Figure 1 is a plan View of my invention. Fig. 2 is a detail view of the bearing devices for the trailing marker-shaft.

Referring to the drawings, it will be observed that I have confined myself to the illustration of just the framework of my in vention and have but slightly set forth the hopper or hopper-actuating mechanism. The

reason for this is that the gist of my invention is confined to the attachment'of the spadewheel marker-shaft A to the frame B, carried by the ground-wheels O O.

The frame B is substantially rectangular and is intersected at aboutits center of length by the stationary shaft or axle a, on which said ground-wheels are journaled. The front end of this frame is either articulately or rigidly secured to the hopper-frame B, which latter has secured to the ends of its parallel transverse members the usual furrow-openers b b and hoppers c c of any suitable construction. The tongue E of the check-rower is rigidly secured to the transverse members of the hopper-frame, so as always to be in longitudinal alinement with the sides of frame B.

The rear transverse member of frame B has corresponding cross-links d d pivoted thereto at or near the ends of the same, and these links have their rear ends pivotally connected to clips 6 e, in which shaft A is journaled. In order to prevent the independent longitudinal movement of shaft A in its bearings, I

prefer to provide it with the collars f f, which, as shown, are placed next to and in contact with bearing-clips 6. This may be accomplished in any suitable manner.

Journaled in the side members of frame 13 near their forward ends isa transverse shaft F, which at about its center of length is provided with a sprocket-wheel h, through the medium of which and an endless chain H engaging therewith and with a sprocket-wheel 9 it is driven by shaft A, at about the center of length of which the latter sprocket g is secured. Near the sprocket h shaft F is provided with a wheel G of suitable diameter, which is provided with a number of laterallyprojecting lugs arranged at equal intervals apart, which during the revolution of shaft F engage an arm k, projecting rearwardly from a transverse rock-shaft K, which leads to and constitutes the actuating-shaft for the seed-feeding devices.

What I claim as new isl. The combination with the frame of a check-rower, of a marker-shaft, and revolving markers on the ends thereof, and crossed links connecting said shaft to said frame.

2. The combination with the parts of a check-rower the relative position of which to the draft-rigging is always the same, and said draft-rigging, of a marker-shaft, revolving markers on the ends of the same, and crossed links connecting said shaft to said parts.

3. The combination with the parts of a check-rower the relative position of which to the tongue is always the same,and said tongue,

of a marker-shaft, revolving markers on the ends of thesame, and crossed links connecting said shaft to said parts.

4:. The combination with the parts of a check-rower the relative position of which to the draft-rigging is always the same, and said draft-ri ggin g, of a trailing transverse markershaft, revolving markers on the ends of the same, and crossed links connecting said shaft to said parts.

5. The combination with the rectangular frame of a check-rower,wheels supporting the same, a rigid tongue therefor, and links pivotally secured at or near the rear angles of said frame and crossed, of a marker-shaft, bearing devices for said shaft which are pivotally connected to the rear ends of said links,

and revolving markers on the ends of said marker-shafts.

6. The combination With supporting-frame of a check-rower,draft-rigging rigidly secured thereto, a transverse marker-shaft, and revolving markers on the ends thereof,of crossed links connecting said supporting-frame and marker-shaft which cross at a point alining with said draft-rigging when said markershaft is in its transverse position.

7. The combination with a rectangular frame of a check-rower, supporting-wheels for the same, a transverse hopper-frame secured to the front end of said rectangular frame, and a tongue rigidly secured to said hopper-frame, hoppers, seed-feeding devices therefor, of a transverse marker-shaft operatively connected to said devices and crossed links connecting the same to the rear of said rectangular frame.

8. The combination with a rectangular frame of a check-rower, supporting-wheels for the same, a transverse hopper-frame articulately secured to the front end of said reetangular frame, and a tongue rigidly secured to said hopper-frame, hoppers, seed-feeding devices therefor, of a transverse marker-shaft operatively connected to said devices, and crossed links connecting the same to the rear of said rectangular frame.

9. The combination with the supportingframe of a check -rower, wheels therefor, transverse hopper-frame secured to the forward end of the same, hoppers, seed-feeding devices therefor, and a transverse shaft journaled in the forward part of said supporting-' frame, of a trailing transverse marker-shaft links connecting the same to said supportingframe and devices connecting said markershaftand transverse shaft.

10. The combination with the supportingframe of a cheek-rower, wheels therefor, transverse hopper-frame secured to the forward end of the same, hoppers, seed-feeding devices, and a transverse shaft journaled in the forward part of said supporting-frame, of a trailing transverse marker-shaft links connecting the same to said supportingframe, and an endless chain and sprocket-Wheels connecting the said marker-shaft and transverse shaft about their centers of length.

11. The combination with the supportingframe of a check rower, wheels therefor, transverse hopper-frame secured to the forward end of the same, hoppers, seed-feeding devices therefor mechanism for actuating the same, and a transverse shaft engaging said actnatin g mechanism j onrnaled in the forward portion of said supporting-frame, markershaft, revolving markers on the ends of the same, crossed links connecting said markershaft and supporting-frame,and endless chain and sprocket-Wheels connecting said markershaft and transverse shaft.
